It is important to have a secure and reliable access control mechanism for any sensitive case. Medical emergency department is also such type of area where we need a good access control mechanism. So by using PBAC, we can make a reliable access control so that doctors, nurses, patients have sensible access control over there. In PBAC, users do not need to use any complicated things to access into the resource. In this paper, we have found some limitations of the current system. Currently there are 3 types of roles. We have suggested for I) using four types of access level: Unauthenticated user access, Nurse Access, Doctor Access, Administrative access, II) setting a notification system to improve this system III) handling multiple user situation and IV) handling critical situation. There are also problems for overlapping. Two or more proximity zone can overlap with one another and there will be a difficult situation for making a good management of the resource. We worked on that to make it more efficient. Inner zone notification is the addition of this model because person residing in the inner zone cannot be notified about the outsider, so if he can finish quickly or leave if it is not so important then it would be better. Our proposal meets critical situation also. The goal of our work is to make a more secure environment, so that user will be relaxed from worrying about security and trouble. As we want to make a best system for treating patients so that it can make the best way to treat patients. We have vision to improve existing ED work flow by automating certain mundane activities so that care givers can only focus on patient rather than authentication.
